Title: Adversity in safety studies: How to set a NOAEL?

This meeting addresses the contemporary view on “Adversity in animal studies” and its consequences for deriving a NOAEL. The reason for this meeting is the flared up discussion whether to include organ function in setting a NOAEL, as recently supported by the Society of Toxicological Pathology (STP) in 2 of their recent publications. To underline the actuality of this topic, the EFSA recently published a Guidance of Biological Relevance which is open for comments (see link below).

In the first part of the meeting, the STP position on “adversity” will be highlighted and an alternative view on “adverse” will be presented. In a concluding presentation a comparison will be made of the potential consequences of the new concept of adversity on both the NOAEL and Bench Mark Dose approach.

In the 2nd part of the meeting, the new concept of adversity will be dealt with in an interactive workshop in which the attendees will discuss in small groups the setting of a NOAEL for a number of case studies.
